In principle, I think so, but there a lot of technical barriers to learning how to actually make the structures you’d need to do it. (I haven’t read the actual paper because of the paywall) From my understanding, there are (at least) 3 factors responsible for the high strength - nanoscale geometry, basically the can 3D print nanoscale truss structures - nanocrystalline base metal. There are established methods for fabricating bulk nanocrystalline metals [0], but doing it in an additive manufacturing process at bulk scale I think is a totally open question - they’re getting extra strength from residual porosity in the metal grains (the pores pin dislocations, stopping one of the principal deformation mechanisms [1]). This is a well known phenomenon, but getting uniform nanoscale pore structure sounds really hard, especially in a bulk metal, and extra especially in an additive setting 0: https://en.m.wikipedia.org/wiki/Nanocrystalline_material# https://en.m.wikipedia.org/wiki/Nanocrystalline_material# 1: https://en.m.wikipedia.org/wiki/Dislocation https://en.m.wikipedia.org/wiki/Dislocation 1b: https://en.m.wikipedia.org/wiki/Zener_pinning https://en.m.wikipedia.org/wiki/Zener_pinning
